<p>Markdown是一种可以使用普通文本编辑器编写的<a href="https://baike.baidu.com/item/标记语言/5964436" target="_blank" rel="noopener">标记语言</a>，通过简单的标记语法，它可以使普通文本内容具有一定的格式。</p>
<p>Markdown具有一系列衍生版本，用于扩展Markdown的功能（如表格、脚注、内嵌HTML等等），这些功能原初的Markdown尚不具备，它们能让Markdown转换成更多的格式，例如LaTeX，Docbook。Markdown增强版中比较有名的有Markdown Extra、MultiMarkdown、 Maruku等。这些衍生版本要么基于工具，如Pandoc；要么基于网站，如GitHub和Wikipedia，在语法上基本兼容，但在一些语法和渲染效果上有改动。</p>

<h3 id="图片"><a href="#图片" class="headerlink" title="图片"></a>图片</h3><p>使用Markdown将图像插入文章，你需要在Markdown编辑器输入 <code>![]()</code> 。 这时在预览面板中会自动创建一个图像上传框。你可以从电脑桌面拖放图片(.png, .gif, .jpg)到上传框, 或者点击图片上传框使用标准的图像上传方式。 如果你想通过链接插入网络上已经存在的图片，只要单击图片上传框的左下角的“链接”图标，这时就会呈现图像URL的输入框。想给图片添加一个标题, 你需要做的是将标题文本插图中的方括号，e.g;<code>![This is a title]()</code>.</p>
<h3 id="脚注"><a href="#脚注" class="headerlink" title="脚注"></a>脚注</h3><p><strong>脚注不存在于标准Markdown中。</strong></p>
<p>使用这样的占位符号可以将脚注添加到文本中:<code>[^1]</code>. 另外，你可以使用“n”而不是数字的<code>[^n]</code>所以你可以不必担心使用哪个号码。在您的文章的结尾，你可以如下图所示定义匹配的注脚，URL将变成链接:</p>
<figure class="highlight plain"><table><tr><td class="gutter"><pre><span class="line">1</span><br><span class="line">2</span><br><span class="line">3</span><br><span class="line">4</span><br><span class="line">5</span><br></pre></td><td class="code"><pre><span class="line">这里是脚注[^1]</span><br><span class="line">[^1]: 这里是脚注的内容</span><br><span class="line"></span><br><span class="line">这里是脚注[^n]</span><br><span class="line">[^n]: 这里是脚注的内容</span><br></pre></td></tr></table></figure>
